Aerospace Engineering questions with complete
solution
Aerospace Engineering - correct answer>>>focuses on
designing, building, analyzing, and troubleshooting
components of aircraft, spacecraft, missiles, and high-altitude
vehicles
Aeronautical Engineering - correct answer>>>deals with
aircraft that operate within the Earth's atmosphere
Astronautical Engineering - correct answer>>>- deals with
manned and unmanned aircraft that operate outside of the
Earth's atmosphere
- design considerations are more complicated
- must consider safety of crew, cost to operate, cargo, and type
of craft being launched
- modern spacecraft are designed, built, and operated by the
government or private companies
Professional Society - correct answer>>>American Institute of
Aeronautics and Astronautics (AIAA)
Employers - correct answer>>>Department of Defense
NASA
McDonnel Douglas, Hughes, Curtiss-Wright
Aerodynamics - correct answer>>>- study of how air flows
around solid objects
- affects everything that moves
- relies on understanding of the conservation of mass,
momentum, and energy
- aircraft are designed as as aerodynamic as possible
- surfaces designed to be smooth and create least possible
wind resistance
- aerodynamic planes fly more efficiently
Lift - correct answer>>>when the wing creates a downward
force on the air, which creates an upward force on the wing
Bernoulli Theory of Lift - correct answer>>>increased speed of
air on top of wing creates lower pressure-- causing lift
Newtonian Theory of Lift - correct answer>>>as air particles hit
the bottom of the wing, lift is created
